IMPROVEMENT !N MACHINES FOR SEWING TURNED SHOES.

Specification forming part of Letters Patent No. 140,586, dated July P3,1873; application filed May 16, 1873.

To all whom it may conce-rn:

Be it known that I, THOMAS L. MILLER, of the city of Philadelphia andState of Pennsylvania, have invented an Improvement in Sewing-Machinesfor Turned Shoes, of which the following is a speciteation:

My invention relates to thefollowing particulars: The channel-opener isattached to the stock, having a fixed position in relation to theneedle, and traveling back and forth with it. The rest is attached tothe standard, and is capable of adjustment by means of slots, throughwhich conningscrews pass to accommodate changes in thelength of thestitches. A spring-catch fastened to the head of the goose-neck isoperated by suitable mechanism for holding the presser-foot down in apositive position. The beveledge guide is adjustable by meanslot' alever connected with a toothed rack. A horizontal and verticaladjustment together are given to the bevel-edge guide when the distance,toy be sewed through is changed, as is necessary when the machine ischanged for either spon gy or solid leather.

Figure lis a front elevation of the machine. Fig. 2 is a side elevationofthe same. Fig. 3, Sheet No. 2, is a side elevation taken at the.opposite side of the machine from that of Fig. 2. Fig. 4 is aperspective view of the lever It,

- having on its front end the bevel-edge guide S. Fig. 5 is a like viewof the adjustable extension-piece R' of the lever It. Fig. 6 is a likeview of the spring-catch N Fig. 7 is a view of the adjustable stop-plateQ detached from the spring-catch N. Fig. Sis a perspective view of theadjustable rest K.

Like letters in all the figures indicate the same parts. A is the base,and B the goose-neck, of an ordinary sewingmachine having thedrivingshaft C, provided with a cam-wheel, D, stock or slide E, carrying the needle-bar F, cast-0H bar G, and channel-opener H. The presserfootrod I and looper-rod J are operated by the cam-wheel D on thedriving-shaft C in the usual manner. The stock E is driven by therock-shaft C', seen in detail in Fig. 1. The rest K isadjusta-ble on thestandard -L by means of slots a a, through `which screws b b pass intothestandard to suit changes in the length of the stitches. The rest isseen in detail in Fig. 8. By the arrangement of the channel-opener II atthe opposite side of the needle-bar to that of the rest K the openerbecomes also a rest, so as te make another support to the shoe, theneedle passing bctween it and the rest K; and, as the cliannel openerhas a lateral movement with the needle-bar, it may be placed very nearto it, and give a rm support to the shoe, so that the stitches may bemore tightly drawn than without such arrangement. The presser-foot M onthe rod I is held down in a posit-ive position by means of thespring-catch N falling into connection with the notched stop O,adjustable on the rod by means of the screw d, the spring-catch beingpressed from the stop 0 to release. the presser-ibut before the feedingmotion is given by means of a vertical movement of the rod P imparted bythe slotted arm c of the rock-shaft C, the incline j' on the upper endot' the rod bearing against the stop g of the plate Q, which isadjustable by means of the slot h, seen in Fig. 7. The plateis fastenedto the spring-catch by means of the screw i. R is a lever, provided atits front end with the bevel-edge guide S. It is hung, by means of thescrew T, tothe standard L, seen clearly in Fig. 2. The lever has anextension-piece, It', the rear end of which engages with the xed rack U.The lever R has slots j j, as seen in Fig. i4, through which passes thescrew T, which also serves as a fulcrum for the lever, and to secure thefront end ot ItV and the screw Tf, which .confines the extension-pieceIt', to the lever. By means of the said slots j j and the rack U thebevel-edge guide S has an adjustment bot-h vertically'and horizontallybackward or forward when the distance to be sewed through is changed, asis necessary when the machine is changed for either spon gy or solidstock.

1. The combination and arrangement ol' the rest K with the standard L bymeans of lthe screws b b and slots a va., to admit of the lateraladjustment of the rest when cha-nge is made in the length ot' thestitches, substantially as set forth.

2. The combination of the springcatch N, notched stop O on thepresser-foot rod I, and the vertical rod P with the roek-shait C', for

2 riflos holding the presser-foot ziown and releasing it, substantiallyas described.

3. The combination of the lever l, having he beveLedge guide S on itsfront end and an i-xtensiou-pieee R,`the standard L, and rack i', i orvarying the hei ght and forward or backward position of said guide S,substantially :as and for the purpose set; forth.

4. The combination ofthe stationary rest K,

channel-opener 1I, and needle-bur F, when the lutter is arrangedbetween` the rest und the ehzmnel-opener, and the openerI has ailateral. movement; with the needle-bur, substantially in the manner andfor the purpose set forth.
